[Clinical Analysis of EB Virus Infection Complicated with Hemophagocytic Syndrome and Hodgkin's Lymphoma]

To investigate the clinical characteristics and outcome of parhents with EBV infection conbined with hemophagocytic syndrome and Hodgkin's lymphoma.

The morphotogy of bone marrow cells was observed by bone marrow smear and light microscopy, the pathologic changes of bone marrow ware analyzed by bone marrow biopsy and immunohistochemistry methord, the pathologic changes of lymphonudes ware detected by immunohistochemical methord, the paticnts were treated with ABVD （epirubicin, bleomycin, vincristine and dacarbazine） chemotherapeutic regimen.

Fever complicatid with pancytopenia, obvious increase of ferritin and sCD25, hypofibrinogenemia, hemophogocytic phenomen of bone marrow, increase of EBV-DNA copy number ware observed, which all accorded with the criteria EBV righted hemophagocytic syndrome. The curative efficacy of amtiinfective treatmatnt was poor, After treatment with HLH-2004 regimen, the fever symptome and the laboratory indicaters such as whole blood cells, ferritin and fibrinogen all were recovered to normal levels. Left mandibular lymphadenctasis was confirmed as Hodgkin's lymphoma （mixed cell type） by pathological examination. The patient achieved complete molecular remission after 1 course chemotherapy with ABVD regimen. The level of EBV-DNA copy number were also decreased. As the reshlt, the patient's hemophagocytic syndrome had bean effectively controlled, and the Hodgkin's lymphoma is still in complete remission.

Epstein-Barr virus-ratated hemophagocytic syndrome and Hodgkin's lymphoma are rare, and their long-term prognosis needs to be further explored.
